First of all, you should take a look at this tutorial about Strings and StringBuffers. This should give you a good introduction to the tools available to solve this task. You should also familiarize yourself with the Java API docs. This will give you a handy reference to the classes and methods available from the standard Java API. It is certainly worth your time to learn how to navigate this. For now, you should start by finding the classes in the java.lang package since that is where String and StringBuffer are located.

If you are still having problems after you have familiarized yourself with the classes Layne suggested then post your partial solution here and we'll help you figure it out the rest of the way.
